This invention relates generallyto fishing boats and particularly to aspecial form of driving means therefor.

The main object of this invention is to provide a special form ofdriving mechanism for power boats in which the driving mechanism mayalso be employed to steer, and control the direction of travel of saidboat.

The second object is to produce a propelif ling device for fishing boatswhich will eliminate the necessity of a rudder and also any possibilityof the propeller becoming fouled on the nets.

The third object is to provide a form of if: fishing boat having a novelform of net handling apparatus.

The fourth object is to providea special form of propeller adaptable touse on boats and also on sleds and wheeled vehicles.

fr.) The fifth object is to provide a novel form of reversiblepropeller.

These, and other objects, will become more apparent from thespecification following as illustrated in the accompanying drawings.

ilar parts throughout the several views.

Referring in detail to the drawings, there 50 is shown the hull 15 of afishing boat in the bow of which is placed an engine 16 preferably ofthe internal combustion type on whose power take-od shaft 17 is asprocket pinion 18 which drives the sprocket wheel 19 on thecountershaft 20 Von which is also mounted a sprocket wheel 21. Motion istransmitted from the pinion `18 to the sprocket 19 through the chain 22.p

At the stern of the boat is mounted a cable winding drum 23 which isnormally free to turn on the shaft `24 on which is secured a sprocketwheel 25 which is. driven from the sprocket Vwheel 21 by means of thechain 26. On the shaft 24 is secured a clutch disk 27 adapted tofrictionally engage the drum 23 under control of the lever 28. A bandbrake 29 encircles the flange 30 of the drum- 23 and is controlled inany convenient manner common to such devices. y

Mounted over the stern end 31 of the boat is a horizontal roller 32 atwhose ends are the upright rollers 33 all of which are adapted to guidethe net 34 into ythe form of a narrow web, in which form it passes overthe threading spool 35 suspended from the rocker arm 36 which ispivotally mounted at one end on the-pin 37 which is, in turn, mounted atthe forward end 0f the horizontal plate 38 which extends across thelfull width of the boat and is secured to the sides thereof. The plate 38is provided with a curved slot 39` its center being on4 the center ofthe standard 40 on which is hinged the operating arm 41 whose upturnedend 42 is forked to receive the rocker arm 36 on the top side of theplate 38. n

Motion is imparted to the arm 41 by means of a link 43 which connectssame to a crank gear 44 which, in turn, is driven by a pinion 45 on theshaft 46 which is driven through the bevel gears 47 from the shaft 20.-Suitable standards 48 support the shaft 2O and a standard 49 supports atable 5() on which are mounted the gears 44 and 45. It is desirable thatthe threading spool 35 be provided with lateral freedom to facilitatethe n winding of the net 34 on the drum 23.

The mechanism thus far described relates Turning now to the boatpropelling and steering apparatus at the bow it will be seen to consistprimarily of a pair of air propeller blades 51 each of which isrotatably mounted on its longitudinal axis on a shaft 52 which journalsin the bearings 53 mounted in a hub 54 which is formed on the outer endof the driving sleeve 55 which, in turn, journals in the bearings 56 inthe propeller housing` 57 whose lower portion 58 is rotatably mounted ina bracket 59 which is attached to the bow 60.

From the engine 16 extends a drive shaft 61 which includes a number ofbevel gears 62 for the purpose of delivering a rotative movement to theupright propeller drive shaft 63 which journals in the bearings 64 inthe portion V58 of the-'housingY 57. On the upper end of the shaft 63 isa pinion 65 which 'mesheswith the gear 66 which is keyed directly to thedriving sleeve 55. A suitable thrust bearing 67 is provided between thegear 6,6 and the rhousing 57.

The inner ends of the shaft 52 are provided with square recesses 68-intoeach of which fits a square end 69 of a crank 70. The ends 71 of eachcrank 7 O extends into its respective slot 72 of the propeller pitchcontrolling rod 73 which is threaded into the endiof a central tube 74which is slidably `mounted within the sleeve 55 and on its projectingend 7 5, is secured a grooved collar 76 *which engages a forked arm 77which is keyed on the shaft 78, which ournals in the housing 79.

On the shaft 78 is secured a worm Wheel 8O which meshes with a worm v81on the shaft 82. On the member 58 is secured the'worm wheel 83 whichmeshes with av steering worm 84 which is rotated by means of a shaft 85which journals in the housing 86. The shaft 85 eX- tends through atubular sleeve 87' which ournals in the bearing 88 andA has mounted onits endk a steering wheel 89by means, of which the Worm 8st can berotated and through which the directional position of the propel'- lerblade 51 can be controlled.

The sle-eve 87 has securedy thereon a. wheel 90 by mea-nsv of which thesleeve 87 canv be rotated.l 0n the end of the. sleeve 87 isv secured, agear 91 which meshes with a gear 92 on the shaft93 which journals inthebearing 94C. The shaft 93 is provided with a universal; coupling 95 atone end thereof Which, through a spline shaft 96 and a second coupling97 can` transmit motion to the shaft 8 2. Iny other words, rotation ofthe Wheel 90 will cause a change in the pitch of the propeller blades 51to the extent that the speed of the boat can be varied, as well as itsdirection of travel, by a mere manipulation ,ese

that is, either astern or ahead, as well as to control its course.V Theadvantages of doing so are of course apparent, especially when viewed inconnection Wit-h th-e handling of a net.

Under ordinary circumstances when propellers are employed rudders arealso used, and it is a mattei' of common occurrence to Yhave either therudder or propeller or both become fouled with the nets causingconsiderable losses of time and money.

In order that it will be possible to better control the operation of thethreading spool 35 a clutch 98 is provided on the shaft 46 which willpermit the movement of the arm 36 to be controlled as required.

It will also be noted that with a boat of this type that should samebecome beached in sand orI mnd there is no danger of the propeller orrudder becoming foul-ed thereby. The same of course applies to objectsfloating in the Water.

As previously stated, this device, especial` ly the propelling andsteering portion thereof, is adaptable to land traveling vehicles andsleds as well as to floating objects; I therefore do not wish to belimited to the particular embodiment illustrated in the drawings, butintend to cover all such forms and modifications thereof as fall fairlyWithin the appended claims.

I claim:

1. In a fishing boat the combination of a hull, a net handling drummounted on the stern of said hul-l, fair leading rolls on said hulladapted to narrow the net for winding, a spooling'means lor guiding thenarrowed end along said drum, and a power actuated propeller at the bowofsaid boat having means for varying its direction of pull.

2. In a fishing boat the combination of a hull, a net handling drummounted at the stern of said hull, means for driving said drum, clutchbrake means for controlling the operation of said drum, fair leadingrolls for narrowing a net prior to winding on said drum, and a threadingspool between said fair leading rol-ls and drum having means for movingsame along the facev of said drum for the purpose of smoothly winding anet thereon.

In operation it is only necessary for the operator to start his engineand manipulate thejqontrols 89 and 90, as just described,in order topropel the boat in either direction-
